Technical Abstract

A semiconductor device includes a first n-type transistor and a first p-type transistor that are positioned side by side over a substrate. The first n-type transistor includes a first n-type source/drain (S/D) region, a first n-type channel region, and a second n-type S/D region that are formed based on a first continuous channel structure extending along a horizontal direction parallel to the substrate. The first n-type channel region is positioned between the first n-type S/D region and the second n-type S/D region. The first p-type transistor includes a first p-type S/D region, a first p-type channel region, and a second p-type S/D region that are formed based on the first continuous channel structure. The first p-type channel region is positioned between the first p-type S/D region and the second p-type S/D region. The second n-type S/D region is in contact with the first p-type S/D region.
